Question

In a cuboid,of 3 sides are $4a^2{b}^2,6a^2{b}^2$ and 6a, then the volume of the cuboid is

• A. $144a^5{b}^4$
  
• B. $144a^3{b}^2$
• C. $144a^2{b}^3$
• D. $12a^2{b}^2$

Answer 1

Answer: (A)

$144a^5{b}^4$

Volume of the cuboid$=l\times b\times h$

$=4a^2{b}^2\times 6a^2{b}^2\times 6a$

$=144a^{2+2+1}{b}^{2+2}$

$=144a^5{b}^4$
